After receiving people’s reports, the department sent seawater samples to Hue University of Sciences, Da Nang University of Science and Education, and Viet Nam Institute of Oceanography in Nha Trang City for analysis.

According to the institute, recently, silicon algae has appeared at Da Nang City’s beaches. However, there is little scientific evidence showing that the algae can cause itchy rash and skin allergies.

Therefore, Nam assumed that starfish and jellyfish might be responsible for the skin trouble.
